In an apparatus for cutting pattern pieces and creating apertures in sheet-type work material a frame has a support surface mounted thereon for carrying at least one layer of the work material. A carriage is coupled to the frame for movement back-and-forth there along a first coordinate direction in response to commands issued from a controller. A cutting head is mounted to the carriage and moves in a second coordinate direction along the carriage approximately perpendicular to the first coordinate direction. A rotary die is coupled to the cutting head and at least one cutting tool is mounted to the rotary die. The cutting tool includes a shaped cutting portion corresponding to the shape of an aperture to be formed in the work material. During operation the rotary die is movable between a working position wherein the cutting tool engages the work material and a non-working position wherein the rotary die is positioned away from the work material.

In a resonating assembly, a beam having a pickup thereon is positioned proximate to a magnet which passes across the pick up at a predetermined frequency. The passage of the magnet across the pick up establishes an alternating magnetic field that in turn causes the beam and pick up to vibrate. A blade is mounted on the beam and vibrates therewith so that when the blade is brought into engagement with a layer of sheet type work material the vibratory amplitude of the blade causes the blade to cut through the material as it is moved in engagement therewith.
